query to get complete list of v$ and DBA_ tables in a pdb

hi,

1)

Is there a query to show all the V$ and DBA_ for a pdb while logged in as pdb user with dba privs?

2)

when logged in as dba privileges in pdb I get 16 rows in dict (whatever that is) and 5 rows on dba_tables.

wasn't dict view based on dba_tables???

When running from a pdb - 16 rows

select count(*)from dictwhere table_name like '%V$%';

When running from a pdb - 5 rows

select count(*)from dba_tableswhere table_name like '%V$%';

Oracle 19c

Linux 7

I'm not sure why oracle is so unnecessary complicated or why no one I know knows this.
